HEATING `AND VENTILATING APPARATUS.

SPECIFICATION forming partI ofLetters Patent No. 324,106, dated August11, 1885.

Application filed February 25, [885. (No model.)

The invention consists in the peculiar con.v

struction and arrangement of hot-air fines and passages, air-chambers,and Ventilating-dues with a tire-'place in the lower room and itssmoke-flue, all as hereinafter fully described and claimed.

` Reference is to be had to the accompanying drawings, forming part ofthis specication, in

which similar letters of reference indicate corresponding parts in allthe figures.

Figure l is a perspective view of my improved heating and Ventilatingapparatus as applied to heat two rooms', one above the other. Fig. 2 isa vertical sectional side elevation of the same. Fig. 3 is anenlargedfront sectional elevation, partly broken away. Fig. 4. is an..

enlarged side elevation, partly broken away,

and in section on the line x x, Fig. 3, an-d Fig] 5 is a sectional 'planview taken on the .line y y, Fig. 3and partly brokenaway.

'The letter A indicates a fire-place shown without a grate 5 but'it mayhavea grate tted in it, if desired. At-B is shown a hood tted,

tightly over the dre-place and at the lower end of an air due orchamber, C, which extends upward through the lower room, D, to the closehorizontal partition or wall E,which is about on a level with the doorof t-he upper room of the building.

A smoke-flue, F, leads from the hood B up through the air-chamber C andpartition E, and through an air-chamber, G, opening at g into thc upperroom H, and the due F passes also through the partition I, forming thetop of chamber G, into an upper smoke-due, J, which extends through theroof to receive a chimney top or cap of any approved design. The hot-airoutlet g may be covered by a screen, K, of any suitable character.

The re-place A is peculiarly constructed as follows: I make its exposedback and end walls of common or tire-clay bricks a and hollowcast-metalchambers a, preferably of like size with the bricks a. andopen at their backs, said chambers a being made preferably ofcastiron-onefourth of anA inch thick, and laid in the fire-place wallsend to end, and alternately with 'the bricks a. Between every layer ofbricks a and metal chambers c,I set the metal plates L, which rangehorizontally aroundl therre-place and cross a space, M, about fourinches (more or less).in width, and the outer parts or edges of theplates L are set into the common hard-bri ck wall N back of the space M.The ends of every alternate plate L at the opposite sides and front ofthe lire-place are cut away at the space M, as at Z, and an airinlet, O,is provided at one side of the tireplace front next the floor. With thisconstruction the space M is divided vertically by the plates L into aseriesof smaller chambers, m, opening into each other alternately at thefront of the re-place at both sides, so that 'cold air entering at Owill pass around one chamber mfto the opposite or left side and front ofthe fireplace to escape at Z into the next' higher chamber m, and willtravel back through thisy chamber to escape at the right side ot' thefire-place into the next higher chamber, and so on, the air passingentirely varound the fire-place as it rises to each successively higherchamber m of the series, and

from the upper chamber m, and preferably at or near the center of theback wall of the `iireplace,'the air,l admitted at O, now thoroughlyheated, will enter a flue, I), which ranges upward and opens at p intothe upper hot-air chamber, G, and pass to the upper room, H, for heatingit,vthe re in the fireplace A thus serving to heat both rooms D and H,the flue F giving oit' heat directly t0 room H, where it passes throughthe airchamber G.

It is evident that the hollow metal chambers a readily take up the heatfrom the lire in re-place A and give it off to the circuitous chambersm, and as many of these chambers a will be used as the weight of theupper duewalls will allow, so as to secure maximum heating effect on theair passing to the upper room, H.

The passage of the smoke-due F through from the chamber C to theroon1,throngh which the air of the room may circulate.

In the smoke-flue F is pivoted the damper j', the stem f of which passesoutward through one of the passages Q R, preferably the upper one, R, asshown, and has suitable connect ing-rods, s S, with any suitabledetents, allowing the damperf to be set for controlling the draft of thefire on the hearth.

The lower room, D, will be Ventilated directly through the hre-place Aand due F, and for Ventilating the upper room, I-I, I provide an air-ue,T, which ranges through the het wall at the side of the hot-air andsmoke iiues G J, so that an upward draft is induced in said ilne T,which has an opening at t into room H, near the iloor, and an upperopening at 1.', communicating with the liuc J, and also with the room Hnear the ceiling, and the opeuingst t have any suitable registers orvalves, U V, respectively fitted to them in room H, either of which maybe opened to ventilate the room into iue J from the top or bottom, asmay be preferred.

At NV is shown a cap covering an opening, fw, into the upper smoke fine,J, which cap may be removed for cleaning out the soot from the ilue J,as may be required.

Any suitable pipe receiving air from out` side the building may connectwith the airiulet O or passage m, so that pure warmed air may besupplied to the upper room, H, instead of admitting the airdirectly fromthe lower room through the inlet O, as will readily be understood.

I may make the hollow air-chambers a', built in the fire-place wall, ofmaterial other than cast metal, the object being to secure by said thinchambers the quick continuous pas- Y sage er radiation of heat from thefire-place to the air-passage m around it.

In building the fire-place A into a wall where it has to supportconsiderable weight of superstructure, the hollow chambers a and solidbrick a will be built up in columns, so that the columns of brick a willsustain the weight, and without danger of crushing the hollow chambersa'.

It is evident that the flue P may consist of a common stove-pipe run upthrough or along side of chamber C, instead of being built into thewall, as shown, and when such a pipe-ilue is used it will give offconsiderable heat to the chamber C, for distribution to the lower roomthrough the openings Q R.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In heating and Ventilating apparatus, the fire-place A, built withhollow walls forming an air-space, M, a series of plates, L, set acrossspace M and cut away alternately at the ends to form a circuitouspassage, m, provided with an air-inlet, andthe exposed wall of thefireplace provided with hollow air-chambers a', substantially as hereinset forth. y

2. In heating and Ventilating apparatus, the combination, withtheiire-place A,constructed with hollow walls forming an air-space, M, aseries of plates, L, set across space M and cut away alternately to formacircuitous passage, m, having a cold'air inlet, and the air-chamber a',built in the hre-place wall of the air-flue P, communicating withpassage m,and leading to an upper room to discharge hot air therein,substantially as herein set forth.

3. In heating and Ventilating apparatus, the combination, with theireplace A, built with hollow walls forming an air-space, M, aseries ofplates, L, set across space M and cut away alternately to form acircuitous passage, m, having a coldair inlet, an air-flue, P, leadingupward from passage m, an air-chamber, G, in the upper room, into whichthe flue P discharges the hot air, and the smoke-fine F, leading fromthe fire-place A and passing through chamber G, whereby the air escapingfrom passagel m is further heated by the flue F on its way to room H,substantially as herein set forth.

4. In heating and Ventilating apparatus, the combination, with thefire-place A, hood B, fixed therein, and smoke-fine F, of the airchamberC, inclosing ilue F above the fireplace, and the hot-air-circulationpassages Q It, arranged one above the other in the side wall of saidchamber, connecting it with the lower rooln, substantially as herein setforth.

5. In heating and Ventilating apparatus, the ventilatinglue T, made inthe heated wall along the hotair chamber G and smoke-fiue J, andcommunicating by the lower passage, t, with the upper room, H, and byupper passage, t', with room H and flue J, substantially as herein setforth. b
